Thoughts on the FAST Ez-EFI system??

thanks, that's one of Charley's "toys". Cool car.

Good question.... for a thread jack.

Can't answer it though because I really don't know. Not "moving" technically -- just adding a domicile in a warm climate were I can hot rod a bit. We have a place in Scottsdale -- hate it there. But the kids have made good use of it for college so it's worked out.

I'm doing "due diligence" on the vinoland area first... and then may branch out from there. I have some criteria:

Acreage - no houses on "lots"
Green - and hills
Rural - but with great restaurants
Cute towns
Not too hot in the summer so if you don't want to leave - you don't have to
Close to Pleasanton for the GoodGuys shows
A place people want to come visit
An hour but not more than hour and half from airports

Plug that in a spreadsheet -- it's Napa Valley. Thus looking there first. Not sure I can afford what I want. Prices have not come down there like they have in other places. But I L O V E it there... and I don't even drink!

Greg - check out Paso Robles area. Almost everything but the close proximity to large airports...

Just got my EZ EFI yesterday! I cannot wait to get her running!!!

One question though...

I got off the phone with one of the techs at FAST and he seemed to be in a bit of a rush to get me off the phone but could some explain to me why the EZ EFI could not be run as a Dead Head system?

It says in the directions that you should have a FPR with a vacuum return port so I was like...dang, I have a 5th Gen Camaro fuel pump with a 4th Gen regulator and only a single line to the front. It isn't the end of the world but he didn't necessarily explain why I cannot run it that way. Once he also said I don't need to hook the vacuum line up, then I was confused ever so slightly...lol. If I don't need the vacuum line hooked up to read manifold vacuum, then why should I bother putting it there at all? I have a regulator at the tank. Fuel pressure will be 58 psi at the front.

Shouldn't I be able to tell the system I am at 58psi and run it like that to learn?

I had a rough week at work so could someone drop some knowledge on me please? I am feeling rather dense tonight!

Case in point...this Youtube vid by none other than the Comp group themselves....sure looks dead headed to me!

Does your regulator have a vacuum port?

My set-up is as follows:

Vaporworx tank
5th Gen Camaro intank pump
4th Gen Camaro regulator...4 bar set-up. I am honestly not sure how this is set-up but my guess is that it does not have one.

My question would be, since I am drawing a blank on this one, is how does the stock 4th gen Camaro/Firebird regulate fuel pressure with its dead head set-up if everything is back in the tank? Does the computer control it? I honestly do not know since all I had to do when I swapped a '99 Camaro LS1 in my Trans Am was use a Vette FPR and that was it, I am missing the actual need to have the regulator at all.

Sorry if I am really missing something obvious here slap me in the face with it because I am feeling really stupid tonight...haha

Fuel pressure regulators are just as their name implies - they regulate the fuel pressure. Generally the ones you see on aftermarket installs are ADJUSTABLE and that's the difference in the GM versions which are not.

So this is pretty simple really - you have the pump... the pump makes the pressure... so somewhere in your plumbing - you need to install an ADJUSTABLE and VACUUM REFERENCED regulator...

Most injectors are rated at 43 #'s.... if you bump the pressure up from there - they flow more fuel.

If you mount your adjustable vacuum referenced fuel pressure regulator back near the tank -- you'll only have to add a simple RETURN line from the return side of the regulator back to the tank. All this does is bleed off any fuel pressure beyond what you've set it for (requires a gauge to read and set). You actual intake manifold and injectors would then appear to be a deadhead system.

Now - having said all of this - if your injectors are rated at the installed fuel pump pressure. AND if the ECU can be set to the matching fuel pressure.... then you're good to go. I have the EZ EFI and I just input the pressure I set manually at the regulator so that it has this information. There is no "set" pressure - it will ask you during set up - what injectors you have and what pressure you are running.

good info Greg. That's where I was going with the regulator. Since the guy (who shall remain nameless) that I'm doing an EZ EFI install for won't tell me how he wants things done............. I'm going to do a rear regulator install like I do on all my EFI conversions. I just run a vacuum reference line back to the regulator. Many said it'd be slow to react, but I haven't seen any issues in the past doing it this way.

One thing I will point out though, fuel pumps do not make pressure.............

Jody -- I wish they had a "finger" icon.

Remember the audience to which we speak... to most folks - pumps make pressure.

Actually - should we get into telling this poor guy that VACUUM will make his fuel boil?
